UNITED STATES LESTER S. GUNDERMAN, OF PITTSBURGH, PENNSYLVANIA.

MECHANICAL TOY.

Application filed July 16, 1925. Serial No. 43,960.

To all who/m, t may concern.'

Be it known that LESTER S. GUNDERMAN, citizen of the United States, residing at 251 `Kennedy Ave., N. S., Pittsburgh, in the county of Allegheny and State of Pennsylvania, has invented certain new and useful Improvements in Mechanical Toys, of which the following is a specification.

This invention is fora mechanical toy of the type in which a miniature vehicle has rapid downwaiidly travel in a track, power means being provided for raising the vehicle from a lower level to a higher level.

The objects of the present invention are to provide a simple toy which can be cheaply manufactured, the primary object of this invention being to provide means for di i'ecting a vehicle down an incline path through a loop to the other end of the track, then by rocking the track `the vehicle is raised to a higher level to gravitate back to its initial position.

Referring to the accompanying drawing,

Fig. 1 is a top plan view of the toy, with the car removed.

Fig. 2 is a horizontal section on line A-A of Fig. 1 and shows the car in an ele# vated position.

Fig. 3 is a cross section on line B-B'of F 2.

ln the drawing the device comprises a base, which is preferably in the form of an inverted shallow tray, upon which is mounted a pair of uprights 7, in the upper end of which is mounted a swinging frame 8, by pivot bearing 9.

1n the swinging frame 8 is mounted a loop Y 10. The pivot bearings 9 being in a line with the center of the loop section 10, at each end of the loop section are removable end sections 11 having a pair of parallel lugs 13 bent downward below the surface of the track, these lugs fit into parallel slots 12 in the loop section in such a manner as to forni a substantial detachable joint.

rllhe track is made with these removable sections 11 in order to'minimize in space in packing the toy and in shipping. The entire track therefore comprises three seotions and 11-11. The outward end of the removable sections 11 have reversely sloping ends 14 and ends 16 forming a stop to prevent a rolling object or vehicle hereafter described from rolling ofi' the track. The sloping ends 14 are for retaining the rolling object from rolling along the track until it is sufliciently elevated so that` it will gain sufficient momentum to gravitate around the loop section 10 of the track..

The rolling object 15 may be of any suitable means, but l prefer to use a wheeled vehicle.

Mounted on the base 6 is a spring motor 17 of any conventional type of clock work mechanism, mounted on the motor shaft is a crank arm 18. This arm is connected to one end of a connecting rod 19 by a pivot pin 20. The opposite vend of the connect ing rod 19 being connected to the swinging frame 8 by pin bearing 21, in such a manner that the crank 18 of the spring motor rotates, driving the rod 19, the frame 8, and the track section 10 will swing to alter` nately raise the track sections 11.

The operation of the toy may now be ldescribed. Assuming that car 15 to be in a position as shown in Fig. 2, the motor rotating, the crank 18 will cause the arm 19 to swing the loop A10 raising one track end 11, the car 15 will descend the incline portion of the track, around the loop section 10 to the opposite end of the track where it is retained until the track is sufficiently elevated for the car to gain momentum enough in its descent to gravitate back to the opposite end of the track and be elevated to its initial position.

I claim as my invention.

1. A mechanical toy comprising a'base, a track having reversely incline surfaces, havinga loop therein and pivotally supported in the center thereof above the base, car retaining terminals at each end of the track, operating means supported on the base to alternately elevate the ends of the track and a car adapted to rollen the track.

2. A mechanical toy including a base, a loop having a cent-ral pivot support above the base, the track at each end of the loop being inclined, means on the base for alternately elevating each end of the track and alternately lowering the opposite end.

3. A mechanical toy having a loop cen-v trally pivoted suspending the track with reversely inclined surfaces, car retaining terminals at each end of the track, operating means on the base to alternately elevate each end of thetrack and alternately lower the opposite end, and a car adapted to roll on the track. .Y i

7 f1. A mechanical toy comprising ajbase, a

track with reversely incline surfaces, a loop' Cil CTI

there between'pivotally supported above the base, said pivot being substantially the center of the loop, means to alternately elevate and lower the opposite ends of the tracks and a ear adapted to roll by gravity on the track.

5. A mechanical toy con'iprising a base, a track with reversely incline surfaces slop, ing toward each other, a pivotally suspendl" ed loop interposed between the ends of the rocking the track to elevate an object to gravitate to the opposite end of the track.

In testimony whereof I have affixed my signature.
